Let take a sample inequality equation
  x + 3 <    8
  x =  8-3 =    5              just treat it like an equality equation
so the answer is          x < 5
but one thing you must  note, when you change the negative sign of x to positive
 you must reverse the inequality sign
ex:        - x + 3 < 8
             -x =   8-3 = 5            / . - 1
             x  >  -  5            note     I reverse the inequality sign
